SECTIONAL PACKING GLAND AND WASHER.

Application led rOctober 29,1925. Seral'No. 65,702.

rhis invention relates to `an improvement in sectional packing glands orwashers and the present application is :i continuation in part ot myco-pending application for windmills, tiled April 30,1923, Serial No.635,614.

rlfhe object ot' the lpresent invention is `to provide a sectionalpacking gland or Washer which. may bc assembled on a shaft or othermechanical. element without the necessity of taking down the shaft orren'loving objects.

mounted or keyed thereon, the sections of the gland or washer beingmoved laterally onto the shaft and into operative engagement 'ith eachother.

A further object is to provide a sectional packing gland or washerhaving these advantages and capacities and in which the sectionswhenassei'nbledare interlocking so to hold themselves against displacen'ienttrom the shaft or member on which they are mounted.

A still further object is to provide a sectional Hacking gland of thecharacter speciiied and which provides an eifective packing to excludedust and dirt and prevent escape o1 oil or lubricant, the packing glandbeing adjustable to take up for wear as it occurs.

A further object is to provide a packing gland having these advantagesand capaci ties and which is of simple and durable construction,reliable and eiective in operation and comparatively inexpensive tomanufacture and apply.

Other objects and advantages reside in certain novel 'features of theconstruction, arrangement and combination of parts which will behereinafter more fully olescribed and particularly pointed out in theappended claim, reference being had to the accon'ipanying` drawingsJroi-ming a part of this speciiication, and in which:

Figure 1 is a. view partly in vertical section and partly in sideelevation showing the invention embodied in a packing gland and appliedon a windmill,

Figure 2 is a plan view of one of the parts of the packing gland,

Figure 3 is a perspective view thereof,

Figure 4 is a group View in plan showing the sections oil the partillustrated in Figs. 2 and 3 prior to assembly, and

Figure 5 is detail perspective view showing the invention embodied in asectional washer.

ln the drawings, the numeral 1 designates generally a Windmill which hasa shaft 2 rotatably journaled in bearings 3 provided on a housing 4 inwhich a lubricant reservoir 5 is mounted.

The present invention proposes the provision of packing glands 6 one ofwhich is located at the outer end of each o'lj' the bearings 3 toexclude dust and dirt 'from the bearings and to prevent escape of thelubricant supplied to the bearings yfrom the reservoir 5. The packingglands are each of similar construction and each includes a pairo'fcomplenientary members 7 and 8. rfhe member 7 has a collar or annularflange 9 extending from its inner tace and spaced inwardly from the wallof a central opening in said member, and the member 8 has a tlange 10extending'. inwardly from the wall of its central opening and which isadapted to lit snugly in the flange 9, the flanges or collars 9 and 10serving to compress between the member 7 and 8 a suity' able packing 11and force the packing into engagement with the shaft 2 when the parts iand 8 are drawn together and against the bearing housings. Each oi themembers 7 and 8 includes sections 12 and 12a. Each or' these sectionshas a body portion shown yat 13 and 13a, respectively. The body portion13 of section 12 has reduced extensions 14 and 15 at its ends, theextension 14 being co-planar with the inner face of the body 13 andbeing offset from the outer 'face thereof, while the extension 15 isco-planar With the outer face of the section 12 and offset from itsinner face. The extensions 14 and 15 terminate in transversely reducedlongitudinally extending tongues 16 and 17. At the juncture of theextensions 14v and 15 with the body portion 13, Zig-Zag shoulders 18 and19 are provided. The body 13a oit' the section 12L has reducedextensionsy 14il and 15a at its ends and the extension 14CL is co-planarwith the inner face ot the body portion 13l of section 122L and oifsetfrom its outer face while the extension 15l is cov-planar with the outertace of section 12u and offset Yfrom its inner face. The extensions 1421and 15n terminate in transversely reduced tongues 1G and 17a. Theextensions 14a and 15n are provided at their inner ends on oppositefaces of the sections with Zig-zag shoulders 182L and 19, as shownclearly in Fig. 4. The sl'ioulder 18 of section 12 is designed to abutthe extremity of the extension 15a and the tongue 17a of section 12awhen the sections are assembled, while shoulder 19 of section 12 abutsthe extremity of section 14a and the tongue 16 of section 12a. Due tothis interengagement oi the parts, the parts of the'glands areinterlocked in the assembly.

ln order to hold the parts of the glands together and to cause theseparts to exert the requisite pressure on the. packing. confined betweentheir collars, the parts 8 are provided with apertured ears 2l whichregister with similar1 ears 22 provided on the housing of the adjacentbearings and With which suitable t stening devices, such as screws andnuts co-act and When the nuts are tightened the members 7 Will beclamped tightly against the housing.

As illustrated in Fig. the invention is adapted for embodiment in aWasher, indicated at 1W and which is identical with the parts 7 of thepackingglands except that the collars or annular flanges 9 thereof areomitted. In. all, respects the description hereinabove applies to thesectional Washer.

It to be understood that the invention Whether embodied in a packing`gland or in a Washer is constructed of metal having` sufficientresiliency to enable its parts to be assembled in the manner hereinabovedescribed. l f

I claim In. a device ot' the. cl ss described a packn ing` glandincluding a pair ot complementary members having'` telescoping,- collarsextending troni their inner faces, each member' comprising tw'osections,each section llavingg a body with reduced extensions at its endsterminating transversely reducedl tace of one extension ofA tongues, theouter each section being co-planar With the outer tace ot the body otsaid' section and the other tace of said extension being' ollset fromthe inner face olv said section, theother eX- tension of said sectionhaving` one face coplanar with the inner tace of the body et the sectionand the other 'face offset 'from the outer 'l'ace ot the section,Zig-zag shoulders formed at the 'junction'ot the extensions with thebodies ot sec-tions, the shoulders et one section abutting; theextremities of the extensions and tongues of the other section wherebythe sections are interlocled when assembled.
